U.S census bureau data shows that the number of families in the United States (in millions) in year x is given by h(x)= 51.42 + 15.473 + log x, where x=0 is 1980. how many families were there in 2002?
1 answer:
Answer:
C. 72 million
Step-by-step explanation:
Put the appropriate value of x into the correct formula and do the arithmetic.
... For the year 2002, x = 2002 -1980 = 22.
Then the population estimate is ...
... h(22) = 51.42 +15.473·log(22)
... = 51.42 +15.473·1.3424
... = 51.42 +20.77
... = 72.19 ≈ 72 . . . . million . . . . . matches choice C .

Answer:
n=4
Step-by-step explanation:
To get an undefined slope, the denominator has to be zero

This means that x2-x1 = 0
or x2=x1
So 4=n
The answer is C) $30.00.
First, find out how much 1lb costs. 1lb would cost 1/4 of 4lb.
